Abstract : With the development of agriculture technology, people not only pay more attention to increase agricultural production, but ask more requirements for agricultural products’ quality. It promotes all kinds of detection technology applied in agriculture, in which machine visual technology is used widely in the inspection of agricultural products. As the corresponding technology of new sensor is developed, machine visual technology applied in inspection of agricultural products will affect traditional inspection pattern[1]. The current status of machine visual technology applied in inspection of agricultural products will be analyzed in this text. Parts of problems in practical application will be summarized and its future develop direction will be discussed here.
